using Turbo now, but need a new reliable software!

Hi; new to the post = hoping you can help.I have been using Turbo to list on Ebay for 2 years now, and because there is limitations of how many items you can have in the databse and some import/export problems with it, due to huge amounts of time waisted extra on corrections, i need a new software. I would like something that can be downloaded to my computer as Turbo Lister is, because i don't want to be online all the time. anywone can help me with a new listing software i can use for my ebay auctions? thank you very much!
